Water Valve
Assured Automation Water Valve
See attached pictures of the working parts of the Assured Automation water valves used on the 48040, 64040 and 64050 washer extractors in 2002 and early 2003. These were subsequently changed to an angled body valve in production due to intermittent problems with hammer and seat failure.
We installed the valve with the direction arrow pointing toward the water supply and away from the machine.
The valve body has a spring which operates the valve to a closed position. The air is applied to open the valve. However, you could "actuate" the valve to close it if desired. We have no need to do this.
The moving part is the tube with a flange around the outside. The flange sits on the spring and air operates the other side of the flange to open the valve.
The seat is mounted on the back side of the stationary flow "cone". It is a soft black synthetic seat. The tube end seals on this seat.
The valve can open against 125 lb air pressure and worked fine. It also reseated without problem with the arrow pointed toward the air source.
